Front top tooth needs to be pulled bcz of crack. Dentist recommended front tooth to be pulled and then had a bone graft. Then Invisalign braces for 4-5 mos.Then a dental implant. Normal procedure? Why cant i keep the tooth that I have while using Invisalign. Then when my teeth have moved the tooth could be pulled and then a bone graft with the implant. What I have read the bonegraft and implant are done on the same day.Can I have the bone graft done and then 4-5 months down and have the implant?
